# Multidisciplinary Training Areas The PhD program offers eight MTAs for students to choose from. Students are required to declare their MTA by the end of the 2nd semester in the program. See the page [Role and Responsibilities of Co-Directors of MTAs](https://gradschool.mssm.edu/wp-content/uploads/MTA-Co-Director-Role-and-Responsibilities.pdf) for more information. Information about MTAs can be found on the [PhD in Biomedical Sciences Website](https://icahn.mssm.edu/education/phd/biomedical-sciences) and the [PhD in Neuroscience](https://icahn.mssm.edu/education/phd/neuroscience) site.
